Abstract: As quenched microstructure of the Fe 24 6 at% Al 7 5 at% Ti alloy was a mixture of (A2+L2(1)) phases When the as quenched alloy was aged at 1173 K for moderate times the L2(1) domains grew considerably and B2 phase was formed at a/2(100) anti phase boundaries (APBs) as well as phase separation from well grown L2(1) to (B2+L2(1)*) occurred basically contiguous to the APBs where L2(1)* is also a L2(1) type phase With continued aging at 1173K the phase separation would proceed toward the whole well grown L2(1) domains This microstructural evolution has not been reported in the Fe Al Ti alloy systems before [doi 10 2320/matertrans M2010167]
